We usually do a LOT of 05+ spark plugs due to the issue with the lack of threads and weak porcelain, but if you want to DIY there is more than one way to skin a cat but I don't know if I would go the route above necessarily.
- Do it on a cold engine
- Remove the COP's
- Use a can of compressed air (or small pressure air gun off compressor if you have one) to blow out any particulates in each spark plug hole.
- Spray a small amount of penetrating lubricant (pb blaster or even wd40 works fine)
- Start on any plug and start to put some pressure on it turning it. If it makes any screeching or grinding noise add a small amount of spray lubricant, move on to the next plug. Repeat this process until you have them all out.
It helps to have a telescoping magnet or magnetic socket to do this.
I would avoid the back and forth tighten/untighten method described above as that can just further grind inbetween the threads any dirt/grime/metal particulates left in there.
When installing the plugs, remember to use some anti-seize (a little, don't douse em) on the threads and torque to 25 lb/ft.
- Reinstall COP's, connect em, done.
The bottom line is this. If you don't feel comfortable doing this, take it to a professional. There is good reason all the major tool companies make a broken plug removal kit specifically for the 3v head.
If you hear noise when turning the plugs and continue to force them, you will most likely break them in there and it is a PAIN in the ASS to get them out then.
If you REALLY don't want to tackle this and live in the socal area, bring it by and I'll do it for you. Don't worry. I won't tell anyone.
